NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1—DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

The Company

BIOLASE, Inc. (“BIOLASE” and, together with its consolidated subsidiaries, the “Company”) is  a medical device company that develops, manufactures, markets, and sells laser systems in dentistry and medicine and also markets, sells, and distributes dental imaging equipment, including three-dimensional CAD/CAM intra-oral scanners and digital dentistry software.

Basis of Presentation

The unaudited consolidated financial statements include the accounts of BIOLASE and its wholly-owned subsidiaries and have been prepared on a basis consistent with the December 31, 2018 audited consolidated financial statements and include all material adjustments, consisting of normal recurring adjustments and the elimination of all material intercompany transactions and balances, necessary to fairly present the information set forth therein. These unaudited, interim, consolidated financial statements do not include all the footnotes, presentations, and disclosures normally required by accounting principles generally accepted in the United States of America (“GAAP”) for complete consolidated financial statements.

The consolidated results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results for the full year. The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2018, included in BIOLASE’s Annual Report on Form 10-K for the year ended December 31, 2018 filed with the Securities and Exchange Commission (the “SEC”) on March 8, 2019 (the “2018 Form 10-K”).

Liquidity and Management’s Plans

The Company incurred a loss from operations and a net loss, and used cash in operating activities for the three months ended March 31, 2019. The Company’s recurring losses, level of cash used in operations, and potential need for additional capital, along with uncertainties surrounding the Company’s ability to raise additional capital, raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.

As of March 31, 2019, the Company was not in compliance with certain of its loan covenants relating to the SWK Loan (as defined below). In May 2019,SWK Funding, LLC granted the Company a waiver of such covenants. On May 7, 2019, the Company entered into an amendment of its Credit Agreement with SWK Funding, LLC to increase the total loan commitment in the SWK Loan from $12.5 million to $15.0 million, to revise certain of the financial covenants and to issue additional warrants to purchase the Company’s common stock. See Note 15 for additional information.

As of March 31, 2019, the Company had working capital of approximately $13.7 million. The Company’s principal sources of liquidity as of March 31, 2019 consisted of approximately $3.3 million in cash, cash equivalents and restricted cash and $11.7 million of accounts receivable.  

In order for the Company to continue operations beyond the next 12 months and be able to discharge its liabilities and commitments in the normal course of business, it must sell its products directly to end users and through distributors, establish profitable operations through increased sales, decrease expenses, generate cash from operations, or obtain additional funds when needed. The Company intends to improve its financial condition and ultimately improve its financial results by increasing revenues through expansion of its product offerings, continuing to expand and develop its field sales force and distributor relationships both domestically and internationally, forming strategic arrangements within the dental and medical industries, educating dental and medical patients as to the benefits of its advanced medical technologies, and reducing expenses.

7

Additional capital requirements may depend on many factors, including, among other things, continued losses, the rate at which the Company’s business grows, demands for working capital, manufacturing capacity, and any acquisitions that the Company may pursue. From time to time, the Company could be required, or may otherwise attempt, to raise capital, through either equity or debt offerings, or enter into an additional line of credit facility.

Reverse Stock Split

Except as the context otherwise requires, all share numbers and share price amounts (including exercise prices and closing market prices) contained in the unaudited financial statements and notes thereto reflect the one-for-five reverse stock split (“the Reverse Stock Split”) effectuated by the Company on May 10, 2018. See Note 4 below for additional information.

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of these unaudited consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect amounts reported in the consolidated financial statements and the accompanying notes. Significant estimates in these unaudited consolidated financial statements include allowances on accounts receivable, inventory, and deferred taxes, as well as estimates for accrued warranty expenses, goodwill and the ability of goodwill to be realized, revenue deferrals, effects of stock-based compensation and warrants, contingent liabilities, and the provision or benefit for income taxes. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may differ materially from those estimates.

Critical Accounting Policies

Information with respect to the Company’s critical accounting policies, which management believes could have the most significant effect on the Company’s reported results and require subjective or complex judgments by management is contained in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the 2018 Form 10-K. Management believes that there have been no significant changes during the three months ended March 31, 2019 in the Company’s critical accounting policies from those disclosed in Item 7 of the 2018 Form 10-K.

Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market (or, if none exists, the most advantageous market) for the specific asset or liability at the measurement date (referred to as the “exit price”). The fair value is based on assumptions that market participants would use, including a consideration of non-performance risk. Under the accounting guidance for fair value hierarchy, there are three levels of measurement inputs. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable, either directly or indirectly. Level 3 inputs are unobservable due to little or no corroborating market data.

The Company’s financial instruments, consisting of cash, cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities, and the SWK Loan as discussed in Note 9, approximate fair value because of the liquid or short-term nature of these items.

Concentration of Credit Risk, Interest Rate Risk and Foreign Currency Exchange Rate

Financial instruments which potentially expose the Company to a concentration of credit risk consist principally of cash and cash equivalents, restricted cash, and trade accounts receivable. The Company maintains its cash and cash equivalents and restricted cash with established commercial banks. At times, balances may exceed federally insured limits. To minimize the risk associated with trade accounts receivable, management performs ongoing credit evaluations of customers’ financial condition and maintains relationships with the Company’s customers that allow management to monitor current changes in business operations so the Company can respond as needed. The Company does not, generally, require customers to provide collateral before it sells them its products. However, the Company has required certain distributors to make prepayments for significant purchases of products.

8

Substantially all of the Company’s revenue is denominated in U.S. dollars, including sales to international distributors. Only a small portion of its revenue and expenses is denominated in foreign currencies, principally the Euro and Indian Rupee. The Company’s foreign currency expenditures primarily consist of the cost of maintaining offices, consulting services, and employee-related costs. During the periods ended March 31, 2019 and 2018, the Company did not enter into any hedging contracts. Future fluctuations in the value of the U.S. dollar may affect the price competitiveness of the Company’s products outside the U.S.

Recent Accounting Pronouncements

Changes to GAAP are established by the Financial Accounting Standards Board (the “FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification.

The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s consolidated financial position and results of operations.

Adopted Accounting Pronouncements

In February 2016, the FASB established ASU Topic 842 – Leases, by issuing ASU Topic No. 2016-02 (“Topic 842”), which requires lessees to recognize lease on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU Topic 2018-11 – Targeted Improvements. The new standard establishes a right-of-use model (“ROU”) that requires a lessee to recognize a ROU asset and a lease liability for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the statement of operations.

The Company adopted Topic 842 in the first quarter of 2019 utilizing the modified retrospective transition method and a cumulative effect adjustment at the beginning of the first quarter of 2019. The Company has elected the package of practical expedients, which allows the Company not to reassess (1) whether any expired or existing contracts as of the adoption date are or contain a lease, (2) lease classification for any expired or existing leases as of the adoption date, and (3) initial direct costs for any existing leases as of the adoption date. The Company did not elect to apply the hindsight practical expedient when determining lease term and assessing impairment of the right-to-use assets. The adoption of Topic 842 resulted in the recognition of right-of use assets of approximately $0.8 million after a $0.2 million adjustment for deferred rent, and lease liabilities for operating leases of approximately $1.0 million, and no cumulative effect adjustment on retained earnings on its unaudited Consolidated Balance Sheets nor material impact to its unaudited Consolidated Statements of Operations and Comprehensive Loss in the period of adoption. Right-of-use assets are included in Prepaid and other assets, and lease liabilities are included in Accrued liabilities or Other liabilities in the unaudited consolidated balance sheet for the period ended March 31, 2019. See Note 10 — Leases, for additional information.

Recently Issued Accounting Standards

In June 2016, the FASB issued a new standard to replace the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company will be required to use a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. The standard will be effective for the Company beginning January 1, 2020, with early adoption permitted beginning January 1, 2019. We are currently evaluating the impact of this standard on the Company’s consolidated financial statements, including accounting policies, processes, and systems.

NOTE 3 – REVENUE RECOGNITION

Contracts with Customers

Revenue for sales of products and services is derived from contracts with customers. The products and services promised in customer contracts include delivery of laser systems, imaging systems, and consumables as well as certain ancillary services such as training and extended warranties. Contracts with each customer generally state the terms of the sale, including the description, quantity and price of each product or service. Payment terms are stated in the contract and vary according to the arrangement. Because the customer typically agrees to a stated rate and price in the contract that does not vary over the life of the contract, the Company’s contracts do not contain variable consideration. The Company establishes a provision for estimated warranty expense.

Performance Obligations

At contract inception, the Company assesses the products and services promised in its contracts with customers. The Company then identifies performance obligations to transfer distinct products or services to the customers. In order to identify performance obligations, the Company considers all of the products or services promised in contracts regardless of whether they are explicitly stated or are implied by customary business practices.

Revenue from products and services transferred to customers at a single point in time accounted for 84% and 83% of net revenue for the three months ended March 31, 2019 and March 31, 2018, respectively. The majority of the Company’s revenue recognized at a point in time is for the sale laser systems, imaging systems, and consumables. Revenue from these contracts is recognized when the customer is able to direct the use of and obtain substantially all of the benefits from the product which generally coincides with title transfer during the shipping process.

Revenue from services transferred to customers over time accounted for 16% and 17% of net revenue for the three months ended March 31, 2019 and March 31, 2018, respectively. The majority of the Company’s revenue that is recognized over time relates to product training and extended warranties. Deferred revenue attributable to undelivered elements, which primarily consists of product training, totaled approximately $0.6 million and $0.7 million as of March 31, 2019 and December 31, 2018, respectively.

Transaction Price Allocation

The transaction price for a contract is allocated to each distinct performance obligation and recognized as revenue when, or as, each performance obligation is satisfied. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using the best estimate of the standalone selling price of each distinct good or service in a contract. The primary method used to estimate standalone selling price is the observable price when the good or service is sold separately in similar circumstances and to similar customers.

Significant Judgments

Revenue is recorded for extended warranties over time as the customer benefits from the warranty coverage. This revenue will be recognized equally throughout the contract period as the customer receives benefits from the Company's promise to provide such services. Revenue is recorded for product training as the customer attends a training program or upon the expiration of the obligation, which is generally after nine months.

The Company also has contracts that include both the product sales and product training as performance obligations. In those cases, the Company records revenue for product sales at the point in time when the product has been shipped. The customer obtains control of the product when it is shipped, as all shipments are made FOB shipping point, and after the customer selects its shipping method and pays all shipping costs and insurance. The Company has concluded that control is transferred to the customer upon shipment.

10

Accounts Receivable

Accounts receivable are stated at estimated net realizable value. The allowance for doubtful accounts is based on an analysis of customer accounts and the Company’s historical experience with accounts receivable write-offs.

Contract Liabilities

The Company performs its obligations under a contract with a customer by transferring products and/or services in exchange for consideration from the customer. The Company typically invoices its customers as soon as control of an asset is transferred and a receivable for the Company is established. The Company, however, recognizes a contract liability when a customer prepays for goods and/or services and the Company has not transferred control of the goods and/or services. The opening and closing balances of the Company’s contract liabilities are as follows (in thousands):

The balance of contract assets was immaterial as the Company did not have a significant amount of uninvoiced receivables at March 31, 2019 and December 31, 2018.

The amount of revenue recognized during the three months ended March 31, 2019 that was included in the opening contract liability balance related to undelivered elements was $0.3 million, related to extended warranty contracts was $0.7 million and deferred royalties was $3,000.

Disaggregation of Revenue

The Company disaggregates revenue from contracts with customers into geographical regions and by the timing of when goods and services are transferred. The Company determined that disaggregating revenue into these categories depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by regional economic factors.

The Company’s revenues related to the following geographic areas were as follows for the periods indicated (in thousands):

11

Information regarding revenues disaggregated by the timing of when goods and services are transferred is as follows (in thousands):

The Company’s sales by end market were as follows for the periods indicated (in thousands):

The Company acts as the principal in all its imaging equipment distribution sales. The Company takes possession and control of the equipment before they are sold and transferred to the customer. The Company provides the equipment and any related services directly to the customer. The Company has inventory risk before the equipment is transferred to a customer. The Company purchases and obtains the goods before obtaining a contract with a customer. The Company also has discretion in establishing the price sold to the customer for the equipment.

The percentages of the Company’s sales by product line were as follows for the periods indicated:

Shipping and Handling Costs and Revenues

Shipping and freight costs are treated as fulfillment costs. For shipments to end-customers, the customer bears the shipping and freight costs and has control of the product upon shipment. For shipments to distributors, the distributor bears the shipping and freight costs, including insurance, tariffs and other import/export costs.

NOTE 4—STOCKHOLDERS’ EQUITY

Reverse Stock Split

At BIOLASE’s annual meeting of stockholders on May 9, 2018 (the “2018 Annual Meeting”), BIOLASE stockholders approved an amendment to BIOLASE’s Restated Certificate of Incorporation, as amended, to effect a reverse stock split of BIOLASE common stock and on May 10, 2018, the Company filed an amendment (the “Amendment”) to its Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware to effect the Reverse Stock Split, effective as of 11:59 p.m. on May 10, 2018. The Amendment also reduced the authorized shares of common stock from 200,000,000 shares to 40,000,000 shares. Prior year share and per share amounts have been adjusted to reflect the impact of the reverse stock split.

Stock-Based Compensation

2002 Stock Incentive Plan

The 2002 Stock Incentive Plan (as amended effective as of May 26, 2004, November 15, 2005, May 16, 2007, May 5, 2011, June 6, 2013, October 30, 2014, April 27, 2015, and May 6, 2016, the “2002 Plan”) was replaced by the 2018 Plan (as defined below) with respect to future equity awards. Persons eligible to receive awards under the 2002 Plan included officers, employees, and directors of the Company, as well as consultants. As of March 31, 2019, a total of approximately 3.1 million shares of the Company’s common stock have been authorized for issuance under the 2002 Plan, of which approximately 1.0 million shares of the Company’s common stock have been issued pursuant to options that were exercised and restricted stock units (“RSUs”) that were settled in common stock and 1.6 million shares of common stock have been reserved for outstanding options and unvested RSUs, and no shares are available for future grants.

2018 Stock Incentive Plan

At the 2018 Annual Meeting, the Company’s stockholders approved the 2018 Long-Term Incentive Plan (as amended, the “2018 Plan”) which was amended by Amendment No. 1 to the 2018 Plan, approved by the Company’s stockholders at a special meeting on September 21, 2018. The purposes of the 2018 Plan are (i) to align the interests of the Company’s stockholders and recipients of awards under the 2018 Plan by increasing the proprietary interest of such recipients in the Company’s growth and success; (ii) to advance the interests of the Company by attracting and retaining non-employee directors, officers, other employees, consultants, independent contractors and agents; and (iii) to motivate such persons to act in the long-term best interests of the Company and its stockholders.

Subject to the terms and conditions of the 2018 Plan, the number of shares authorized for grants under the 2018 Plan is 3.3 million. As of March 31, 2019, a total 1.9 million shares of the Company’s common stock have been reserved for outstanding options and unvested RSUs, and 1.4 million shares of common stock remain available for future grants.

The Company recognized stock-based compensation expense of $0.8 million and $0.7 million, for the three months ended March 31, 2019 and 2018, respectively, based on the grant-date fair value. Stock-based compensation expense for the three months ended March 31, 2019 and 2018 includes the reversal of $0.1 million and $0.0 million, respectively, resulting from the reassessment of certain performance-based equity awards. The net impact of stock-based compensation expense to earnings was $(0.04), and $(0.03) per basic and diluted share for the three months ended March 31, 2019 and 2018, respectively. At March 31, 2019, the Company had approximately $2.1 million of total unrecognized compensation expense, net of estimated forfeitures, related to unvested share-based compensation arrangements. The Company expects that expense to be recognized over a weighted-average period of 2.0 years.

13

The following table summarizes the income statement classification of compensation expense associated with share-based payments (in thousands):

The stock option fair values were estimated using the Black-Scholes option-pricing model with the following assumptions:

A summary of option activity for the three months ended March 31, 2019 is as follows (in thousands, except per share data):

(1) The intrinsic value calculation does not include negative values. This can occur when the fair market value on the reporting date is less than the exercise price of the grant.

A summary of unvested stock option activity for the three months ended March 31, 2019 is as follows (in thousands, except per share data):

14

Cash proceeds, along with fair value disclosures related to grants, exercises and vested options are as follows (in thousands, except per share amounts):

(1) Excess tax benefits received related to stock option exercises are presented as operating cash inflows. The Company currently does not receive a tax benefit related to the exercise of stock options due to the Company’s net operating losses.

(2) The intrinsic value of stock options exercised is the amount by which the market price of the stock on the date of exercise exceeded the market price of the stock on the date of grant.

Restricted Stock Units

There were no material grants made during the three months ended March 31, 2019.

A summary of unvested RSU activity for the three months ended March 31, 2019 is as follows (in thousands, except per share amounts):

Warrants

The Company issues warrants to acquire shares of the Company’s common stock as approved by the Board. A summary of warrant activity for the three months ended March 31, 2019 is as follows (in thousands, except exercise price amounts):

See Note 9 for additional information on the Western Alliance Warrants, the SWK Warrants, and the DPG Warrants (each as defined below).

15

Net Loss Per Share – Basic and Diluted

Basic net loss per share is computed by dividing net loss available to common stockholders by the weighted-average number of shares of the Company’s common stock outstanding for the period. In computing diluted net loss per share, the weighted average number of shares outstanding is adjusted to reflect the effect of potentially dilutive securities.

Outstanding stock options, RSUs and warrants to purchase approximately 5.7 million shares were not included in the calculation of diluted loss per share for the three months ended March 31, 2019, as their effect would have been anti-dilutive. For the same 2018 periods, anti-dilutive outstanding stock options and warrants to purchase 3.8 million shares were not included in the computation of diluted loss per share.

NOTE 5—INVENTORY

Inventory is valued at the lower of cost or net realizable value and is comprised of the following (in thousands):

Inventory includes write-downs for excess and obsolete inventory totaling approximately $1.1 million and $1.1 million as of March 31, 2019 and December 31, 2018, respectively.

NOTE 6—PROPERTY, PLANT, AND EQUIPMENT

Property, plant, and equipment, net is comprised of the following (in thousands):

Depreciation and amortization expense related to property, plant, and equipment totaled $0.3 million and $0.3 million for the three months ended March 31, 2019 and March 31, 2018, respectively.

16

NOTE 7—INTANGIBLE ASSETS AND GOODWILL

The Company conducted its annual impairment test of goodwill as of June 30, 2018 and determined that there was no impairment. The Company also tests its intangible assets and goodwill between the annual impairment tests if events occur or circumstances change that would more likely than not reduce the fair value of the Company or its assets below their carrying amounts. For intangible assets subject to amortization, the Company performs its impairment test when indicators, such as reductions in demand or significant economic slowdowns, are present. No events have occurred since June 30, 2018 through the date of these unaudited consolidated financial statements that would trigger further impairment testing of the Company’s intangible assets and goodwill.

As of March 31, 2019 and December 31, 2018, the Company had goodwill (indefinite life) of $2.9 million. As of March 31, 2019 and December 31, 2018, all intangible assets have been fully amortized and no amortization expense was recognized during the three months ended March 31, 2019 and 2018.

NOTE 8—ACCRUED LIABILITIES

Accrued liabilities are comprised of the following (in thousands):

Changes in the initial product warranty accrual and the expenses incurred under the Company’s initial and extended warranties for the three months ended March 31, 2019 and 2018 are included within accrued liabilities on the Consolidated Balance Sheets and were as follows (in thousands):

The Company’s Waterlase laser systems sold worldwide are covered by a warranty against defects in material and workmanship for a period of up to 16 months domestically and up to 28 months internationally, from the date of sale by the Company or a distributor to the end-user. The Company’s Diode systems sold worldwide are covered by a warranty against defects in material and workmanship for a period of up to 28 months from the date of sale by the Company or a distributor to the end-user.

NOTE 9—DEBT

The following table presents the details of the principal outstanding and unamortized discount (in thousands):

Line of Credit

On March 6, 2018, the BIOLASE and two of its wholly-owned subsidiaries (such subsidiaries, together with BIOLASE, the “Borrower”) entered into the Business Financing Agreement (the “Business Financing Agreement”) with Western Alliance Bank (“Western Alliance”). Pursuant to the terms and conditions of the Business Financing Agreement, Western Alliance agreed to provide the Borrower a secured revolving line of credit permitting the Borrower to borrow or receive letters of credit up to the lesser of $6.0 million (the “Domestic Revolver”) (subject to a $6.0 million credit limit relating to domestic eligible accounts receivable (the “domestic credit limit”) and a $3.0 million credit limit relating to export-related (the “EXIM Revolver”) eligible accounts receivable (the “EXIM credit limit”)) and the borrowing base, which is defined as the sum of the domestic borrowing base (up to 75% of the Borrower’s eligible domestic accounts receivable less such reserves as Western Alliance may deem proper and necessary) and the export-related borrowing base (up to 85% of the Borrower’s eligible export-related accounts receivable less such reserves as Western Alliance may deem proper and necessary). The Business Financing Agreement was set to expire on March 6, 2020, and the Borrower’s obligations thereunder were secured by a security interest in all of the Borrower’s assets.

The Business Financing Agreement required the Company to maintain compliance with certain financial and non-financial covenants, as defined therein. Western Alliance had the right to declare the amounts outstanding under the Business Financing Agreement immediately due and payable upon a default.

Amounts outstanding under the Business Financing Agreement bore interest at a per annum floating rate equal to the greater of 4.5% or the “Prime Rate” published in the Money Rates section of the Western Edition of The Wall Street Journal (or such other rate of interest publicly announced from time to time by Western Alliance as its “Prime Rate”), plus 1.5% with respect to advances made under the line of credit, plus an additional 5.0% during any period that an event of default occurred and was continuing. The commitment fee under the Business Financing Agreement was 0.25% of the domestic credit limit and 1.75% of the EXIM credit limit, payable on March 6, 2018 and each anniversary thereof. 

Pursuant to the Business Financing Agreement, the Company paid the first of two annual commitment fees totaling $67,500, being 0.25% of the aggregate $6.0 million commitment for the Domestic Revolver and 1.75% of the aggregate $3.0 million commitment for the EXIM Revolver. The commitment fees and the legal costs associated with acquiring the credit facilities were capitalized and were amortized on a straight-line basis as interest expense over the term of the Business Financing Agreement.

As additional consideration for the lines of credit, the Company also issued to Western Alliance warrants (the (“Original Western Alliance Warrants”). The fair value of the Western Alliance Warrants was estimated using the Black-Scholes option-pricing model with the following assumptions: expected term of 10 years; volatility of 91.49%; annual dividend per share of $0.00; and risk-free interest rate of 2.88%; and resulted in an estimated fair value of $0.1 million, which was recorded as a liability and resulted in a discount to the credit facilities at issuance. The discount was expensed to interest expense at the time the Business Financing Agreement was terminated, as discussed below.

18

On August 13, 2018, the Borrower and Western Alliance entered into a Waiver and Business Financing Modification Agreement, pursuant to which Western Alliance waived certain of the Borrower’s covenants under the Business Financing Agreement and provided an advance of $1.5 million, which advance was due by September 27, 2018.

On September 27, 2018, the Borrower and Western Alliance entered into a second Business Financing Modification Agreement which reduced the credit limit under the Business Financing Agreement to $2.5 million and extended the due date of the $1.5 million advance to March 6, 2019. In connection with the agreement, the Original Western Alliance Warrants were terminated, and the Company issued to Western Alliance new warrants (the “Western Alliance Warrants”) to purchase up to 56,338 shares of the Company’s common stock. The Western Alliance Warrants are immediately exercisable and expire on September 27, 2028. These warrants contain down-round features that require the Company to adjust the exercise price proportionately should the Company issue shares at a price less than the $2.13 per share exercise price.

On October 22, 2018, the Borrower and Western Alliance entered into a third Business Financing Modification Agreement, pursuant to which Western Alliance waived BIOLASE’s non-compliance with certain financial operating covenants as set forth in the Business Financing Agreement, and the Borrower agreed to certain amended covenants contained in the Business Financing Agreement, including a $300,000 minimum unrestricted cash balance covenant and a waiver of reporting items required to be delivered by BIOLASE to Western Alliance under the Business Financing Agreement.

On November 9, 2018, all outstanding borrowings, accrued interest and fees under the Business Financing Agreement were repaid with a portion of the proceeds under the Credit Agreement (as defined and described below), and the Business Financing Agreement was terminated. The Company recorded approximately $0.1 million of interest expense including unamortized debt issuance costs that were written-off upon extinguishment of the debt. As of March 31, 2019 and December 31, 2018, the Western Alliance Warrants remain outstanding and are classified in equity in the consolidated balance sheet.

Term Loan

On November 9, 2018, the Company entered into a five-year secured Credit Agreement (the “Credit Agreement”) with SWK Funding LLC (“SWK”), pursuant to which the Company has borrowed $12.5 million (the “SWK Loan”). The Company’s obligations under the Credit Agreement are secured by substantially all of the Company’s assets. Under the terms of the Credit Agreement, repayment of the loan is interest-only for the first two years, paid quarterly with the option to extend the interest-only period. Principal repayments will begin in the first quarter of 2021 and will be approximately $0.7 million quarterly until the loan matures in the fourth quarter of 2023. The loan bears interest at London Interbank Bank Offered Rate (“LIBOR”) plus 10% or another index that approximates LIBOR as close as possible if and when LIBOR no longer exists. Approximately $0.9 million of the proceeds from the SWK Loan were used to pay off all amounts owed to Western Alliance under the Business Financing Agreement. The Company plans to use the remaining proceeds to provide additional working capital to fund its growth initiatives, such as broadening its customer base and increasing the utilization of its products to drive recurring higher margin consumables revenue.

The Credit Agreement contains financial and non-financial covenants requiring the Company to, among other things, (i) maintain unencumbered liquid assets of no less than $1.5 million or the sum of aggregate cash flow from operations less capital expenditures, ii) achieve certain revenue and EBITDA levels during the first two years of the loan, (iii) limit future borrowing, investments and dividends, and (iv) submit monthly and quarterly financial reporting.

In connection with the SWK Loan, the Company paid approximately $1.0 million in debt issuance costs, including a $0.2 million loan origination fee, a $0.4 million finder’s fee, and $0.4 million in legal and other fees. These costs were recognized as a discount on the SWK Loan and are being amortized on a straight-line basis over the loan term which approximates the effective-interest method.

19

The Company recognized approximately $0.5 million in interest expense relating to the SWK Loan for the period ended March 31, 2019. The weighted-average interest rate for the three months ended March 31, 2019 was 12.7%.

As of March 31, 2019, the Company was not in compliance with certain covenants in the Credit Agreement. In May 2019, SWK granted the Company a waiver of such covenants. On May 7, 2019, the Company and SWK agreed to amend the Credit Agreement to increase the total commitment in the SWK Loan from $12.5 million to $15.0 million and to revise certain of the financial covenants. Further details of the amendment are described in Note 15 below.

SWK Warrants

In connection with the Credit Agreement, the Company issued warrants to SWK (the “SWK Warrants”) on November 9, 2018, to purchase up to 372,023 shares of the Company’s common stock. The SWK Warrants are immediately exercisable and expire on November 9, 2026. The exercise price of the SWK Warrants is $1.34, which was the average closing price of the Company’s common stock for the ten trading days immediately preceding November 9, 2018. These warrants contain down-round features that require the Company to adjust the exercise price proportionately should the Company issue shares at a price per share less than the exercise price. The fair value of the SWK Warrants was estimated using the Black-Scholes option-pricing model with the following assumptions: expected term of 8 years; volatility of 81.79%; annual dividend per share of $0.00; and risk-free interest rate of 3.13%; and resulted in an estimated fair value of $0.4 million.

DPG Warrants

In connection with the SWK Loan, the Company paid a finder’s fee to Deal Partners Group of $0.4 million cash and issued warrants to purchase up to 279,851 shares of common stock (the “DPG Warrants”). The DPG Warrants were issued on November 14, 2018, were exercisable immediately, and expire on November 9, 2026. The exercise price of the DPG Warrants is $1.34 which was the average closing price of the Company’s common stock for the ten trading days immediately preceding November 9, 2018. These warrants contain down-round features that require the Company to adjust the exercise price proportionately should the Company issue shares at a price per share less than the exercise price. The fair value of the DPG Warrants of $0.3 million was estimated using the Black Scholes option pricing model with the following assumptions: expected term of 8 years; volatility of 81.79%; annual dividend per share of $0.00; and risk-free interest rate of 3.13%.

The value of both the SWK Warrants and the DPG Warrants was recognized as a discount on the SWK Loan and are being amortized on a straight-line basis which approximates the effective-interest method, over the loan term of five years. Additionally, based on the adoption of ASU 2017-11 in the fourth quarter of 2018, these warrants are classified as equity in the consolidated balance sheet as of March 31, 2019.

The future minimum principal and interest payments as of March 31, 2019 are as follows (in thousands):

NOTE 10— LEASES

The Company enters into operating leases primarily for real estate, office equipment, and fleet vehicles. Lease terms generally range from one to five years, and often include options to renew for one year. On January 1, 2019, the Company adopted Topic 842, using the modified-retrospective approach as discussed in Note 2, and as a result recognized a right-of-use asset of approximately $0.8 million as adjusted for deferred rent at the date of adoption of $0.2 million, and a lease liability of approximately $1.0 million. No cumulative-effect adjustment to retained earnings was required upon adoption of Topic 842. Right-of-use assets are recorded in Prepaid and other assets and lease liabilities are included in Accrued liabilities or Other liabilities depending on whether they are current or noncurrent. Because the rate implicit in each lease is not readily determinable, the Company uses its incremental borrowing rate (“IBR”) to determine the present value of the lease payments and on the date of adoption, the Company determined its IBR to be 12.78%. This rate was based on the Company’s financing of the SWK Loan which is a collateralized loan, and was based on prevailing market rates during the fourth quarter of 2018.

Information related to the Company’s right-of-use assets and related liabilities were as follows (in thousands):

The Company allocates lease cost amongst lease and non-lease components. The Company excludes short-term leases (those with lease terms of less than one year at inception) from the measurement of lease liabilities or right-of-use assets.

Maturities of lease liabilities as of March 31, 2019 were as follows (in thousands):

As of March 31, 2019, right-of-use assets were $0.7 million and lease liabilities were $0.8 million. During the three months ended March 31, 2019, the Company did not enter into any new lease arrangements, nor did it have any arrangements that had not commenced.

Future minimum rental commitments under lease agreements, as of December 31, 2018, with non-cancelable terms greater than one year for each of the years ending December 31 are as follows (in thousands):

NOTE 11— COMMITMENTS AND CONTINGENCIES

On April 24, 2012, CAO Group, Inc. (“CAO”) filed a lawsuit against BIOLASE in the District of Utah alleging that BIOLASE’s ezlase dental laser infringes on U.S. Patent No. 7,485,116 (the “116 Patent”). On September 9, 2012, CAO amended its complaint, adding claims for (1) business disparagement/injurious falsehood under common law and (2) unfair competition under 15 U.S.C. Section 1125(a). The additional claims stem from a press release that BIOLASE issued on April 30, 2012, which CAO claims contained false statements that are disparaging to CAO and its diode product. The amended complaint sought injunctive relief, treble damages, attorneys’ fees, punitive damages, and interest. Until January 24, 2018, this lawsuit was stayed in connection with United States Patent and Trademark Office proceedings relating to the 116 Patent, which proceedings ultimately culminated in a January 27, 2017 decision by the United States Court of Appeals for the Federal Circuit, affirming the findings of the Patent Trial and Appeal Board, which were generally favorable to the Company. On January 25, 2018, CAO moved for leave to file a second amended complaint to add certain claims, which filing the Company is not opposing.

On January 23, 2018, CAO filed a lawsuit against BIOLASE in the Central District of California alleging that BIOLASE’s diode lasers infringe on U.S. Patent Nos. 8,337,097, 8,834,497, 8,961,040 and 8,967,883. The complaint seeks injunctive relief, treble damages, attorneys’ fees, punitive damages, and interest.

On January 25, 2019 (the “Effective Date”), BIOLASE. entered into a settlement agreement (the “Settlement Agreement”) with CAO. Pursuant to the Settlement Agreement, CAO agreed to dismiss with prejudice the lawsuits filed by CAO against the Company in April 2012 and January 2018. In addition, CAO granted to the Company and its affiliates a non-exclusive, non-transferable (except as provided in the Settlement Agreement), royalty-free, fully-paid, worldwide license to the licensed patents for use in the licensed products and agreed not to sue the Company, its affiliates or any of its manufacturers, distributors, suppliers or customers for use of the licensed patents in the licensed products, and the parties agreed to a mutual release of claims. The Company has agreed (i) to pay to CAO, within five days of the Effective Date, $500,000 in cash, (ii) to issue to CAO, within 30 days of the Effective Date, 500,000 restricted shares of common stock of the Company (the “Stock Consideration”), and (iii) to pay to CAO, within 30 days of December 31, 2021, an amount in cash equal to the difference (if positive) between $1,000,000 and the value of the Stock Consideration on December 31, 2021. The Stock Consideration vests and becomes transferrable on December 31, 2021, subject to the terms of a restricted stock agreement to be entered into between the parties. The Company considered this a Type I subsequent event and recognized a $1.5 million contingent loss on patent litigation settlement in its statement of operations for the year ended December 31, 2018. In January 2019, the Company paid CAO $500,000 in cash. On January 31, 2019, the case was dismissed with prejudice. During the three-month period ended March 31, 2019, the Company recorded an additional loss on patent litigation of $0.2 million which represents the change in fair value of the restricted stock to be issued to CAO, resulting in a total $1.2 million accrued liability as of March 31, 2019.

NOTE 12—SEGMENT INFORMATION

The Company currently operates in a single business segment. Management uses one measurement of profitability and does not segregate its business for internal reporting. For the three months ended March 31, 2019, sales to customers in the United States accounted for approximately 59% of net revenue and international sales accounted for approximately 41% of net revenue, respectively. No individual country, other than the United States, represented more than 10% of total net revenue during the three months ended March 31, 2019 or 2018.

Net revenue by geographic location based on the location of customers was as follows (in thousands):  

Property, plant, and equipment by geographic location was as follows (in thousands):

NOTE 13—CONCENTRATIONS

Revenue from the Company’s products for the three months ended March 31, 2019 and 2018 are as follows (dollars in thousands):

No individual customer represented more than 10% of the Company’s revenue for the three months ended March 31, 2019 or 2018.

The Company maintains its cash and cash equivalent accounts with established commercial banks. Such cash deposits periodically exceed the Federal Deposit Insurance Corporation insured limit.

One individual customer represented more than 10% of the Company’s accounts receivable at March 31, 2019 and December 31, 2018.

The Company currently purchases certain key components of its products from single suppliers. Although there are a limited number of manufacturers of these key components, management believes that other suppliers could provide similar key components on comparable terms. A change in suppliers, however, could cause delays in manufacturing and a possible loss of sales, which could adversely affect the Company’s business, results of operations and financial condition.

23

NOTE 14—INCOME TAXES

The Company accounts for income taxes under the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Management evaluates the need to establish a valuation allowance for deferred tax assets based upon the amount of existing temporary differences, the period in which they are expected to be recovered, and expected levels of taxable income. A valuation allowance to reduce deferred tax assets is established when it is “more likely than not” that some or all of the deferred tax assets will not be realized. Based on the Company’s net losses in prior years, management has determined that a full valuation allowance against the Company’s net deferred tax assets is appropriate.

Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return and provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The Company has elected to classify interest and penalties as a component of its income tax provision. With respect to the liability for unrecognized tax benefits, including related estimates of penalties and interest, the Company did not record a liability for unrecognized tax benefits for the three months ended March 31, 2019 and 2018. The Company does not expect any changes to its unrecognized tax benefit for the next 12 months that would materially impact its consolidated financial statements.

During the three months ended March 31, 2019 and 2018, the Company recorded an income tax provision of $15,000 and $32,000, respectively, resulting in an effective tax rate of 0.3% and 0.6%, respectively. The income tax provisions for the three months ended March 31, 2019 and 2018 were calculated using the discrete year-to-date method. The effective tax rate differs from the statutory tax rate of 21% primarily due to the existence of valuation allowances against net deferred tax assets and current liabilities resulting from the estimated state income tax liabilities and foreign tax liability.

NOTE 15—SUBSEQUENT EVENT

As of March 31, 2019, the Company was not in compliance with certain covenants in the Credit Agreement, as described in Note 9. In May 2019, SWK granted the Company a waiver of such covenants. On May 7, 2019, the Company and SWK agreed to amend the Credit Agreement to increase the total commitment from $12.5 million to $15.0 million, and to revise the financial covenants to (a) adjust minimum revenue and EBITDA levels, (b) require the Company to have a shelf registration statement declared effective by the SEC before September 30, 2019, with a proposed maximum aggregate offering price of at least $10.0 million if the Company does not reach set minimum revenue levels for the three-month period ended June 30, 2019, and (c) require minimum liquidity of $1.5 million at all times and if aggregate minimum revenue and EBITDA levels are not achieved by September 30, 2019, the minimum liquidity requirement will be increased to $3.0 million, until the Company has obtained additional equity or debt funding of no less than $5.0 million.

In connection with the amendment, the Company will pay to SWK loan origination and other fees of approximately $0.2 million payable in cash and approximately $0.3 million in additional SWK Warrants to purchase the Company’s common stock. The Company will also pay an additional finder’s fee to DPG, as defined and described in Note 9, of approximately $0.1 million in cash and $0.1 million in additional DPG Warrants to purchase the Company’s common stock.

Overview

We are a medical device company that develops, manufactures, markets, and sells laser systems in dentistry and medicine and also markets, sells, and distributes dental imaging equipment, and digital dentistry software. Our products advance the practice of dentistry and medicine for patients and health care professionals. Our proprietary dental laser systems allow dentists, periodontists, endodontists, oral surgeons, and other dental specialists to perform a broad range of minimally invasive dental procedures, including cosmetic, restorative, and complex surgical applications. Our laser systems are designed to provide clinically superior results for many types of dental procedures compared to those achieved with drills, scalpels, and other conventional instruments. We have clearance from the FDA to market and sell our laser systems in the United States and also have the necessary registration to market and sell our laser systems in Canada, the European Union, and many other countries outside the United States. Additionally, our in-licensed imaging equipment and related products improve diagnoses, applications, and procedures in dentistry and medicine.

We offer two categories of laser system products: Waterlase (all-tissue) systems and Diode (soft-tissue) systems. Our flagship brand, the Waterlase, uses a patented combination of water and laser energy to perform most procedures currently performed using drills, scalpels, and other traditional dental instruments for cutting soft and hard tissue. We also offer our Diode laser systems to perform soft tissue, pain therapy, and cosmetic procedures, including teeth whitening. We have approximately 255 issued and 73 pending U.S. and international patents, the majority of which are related to Waterlase technology. From 1998 through March 31, 2019, we sold over 39,600 laser systems in over 80 countries around the world. Contained in this total are approximately 13,100 Waterlase systems, including over 8,900 Waterlase MD, MDX, Express and iPlus systems.

Business and Outlook

Our Waterlase systems precisely cut hard tissue, bone, and soft tissue with minimal or no damage to surrounding tissue and dental structures. Our Diode systems, which include the Epic system, are designed to complement our Waterlase systems, and are used only in soft tissue procedures, pain therapy, hygiene, and cosmetic applications, including teeth whitening. The Diode systems, together with our Waterlase systems, offer practitioners a broad product line with a range of features and price points.

We also manufacture and sell consumable products and accessories for our laser systems. Our Waterlase and Diode systems use disposable laser tips of differing sizes and shapes depending on the procedure being performed. We also market flexible fibers and hand pieces that dental practitioners replace at some point after initially purchasing laser systems. For our Epic systems, we sell teeth whitening gel kits.

Due to the limitations associated with traditional and alternative dental instruments, we believe there is a large market opportunity for all-tissue dental laser systems that provide superior clinical outcomes, reduce the need to use anesthesia, help reduce trauma, pain, and discomfort associated with dental procedures, and increase patient acceptance for treatment protocols. We also believe there is a large market opportunity for digital radiography systems and CAD/CAM intra-oral scanners that improve practice efficiency and accuracy of diagnosis, leading to superior treatment planning, increased practice revenue, and healthier outcomes for patients.

Our strategy is to increase awareness and demand for (i) our products among dental practitioners by educating dental practitioners and patients about the clinical benefits of our product suite and (ii) our laser systems among patients by educating patients about the clinical benefits of the Waterlase and Diode systems. An important goal of ours is to increase consumables revenue by selling more single-use accessories used by dental practitioners when performing procedures using our dental laser systems. In the short term, we are striving for operating excellence through lean enterprise initiatives, with a specific focus on our sales strategy and cash flow management, coupled with optimizing our engineering capabilities to develop innovative new products.

27

We also seek to create value through innovation and leveraging existing technologies into adjacent medical applications. We plan to expand our product line and clinical applications by developing enhancements and transformational innovations, including new clinical solutions for dental applications and for other adjacent medical applications. In particular, we believe that our existing technologies can provide significant improvements over existing standards of care in fields including ophthalmology, otolaryngology, orthopedics, podiatry, pain management, aesthetics/dermatology, veterinary, and consumer products. We plan to continue to explore potential collaborations to apply our proprietary laser technologies with expanded FDA-cleared indications to other medical applications in the future.

Recent Developments

As of March 31, 2019, we were not in compliance with certain covenants relating to the SWK Loan as defined and described in Part I, Item I, Note 9 above. In May 2019, SWK Funding, LLC (“SWK”) granted us a waiver of such covenants by SWK. Additionally, on May 7, 2019, we entered into an amendment to our Credit Agreement with SWK to increase the total commitment in the SWK Loan from $12.5 million to $15.0 million, to revise certain of the financial covenants and to issue additional warrants to purchase shares of BIOLASE common stock. See Part I, Item I, Note 15 for additional information.

Critical Accounting Policies

The unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and revenues and expenses reported during the period. Information with respect to our critical accounting policies that we believe could have the most significant effect on our reported results and require subjective or complex judgments by management is contained in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the 2018 Form 10-K. There have been no significant changes during the three months ended March 31, 2019 in our critical accounting policies from those disclosed in Item 7 of the 2018 Form 10-K.

Effective May 10, 2018, the Company effectuated a one-for-five reverse stock split (the “Reverse Stock Split”). In connection with the Reverse Stock Split, the number of authorized shares of BIOLASE common stock was reduced from 200,000,000 shares to 40,000,000 shares. All prior period share and per share amounts (including exercises and closing market prices) contained in this discussion have been adjusted to reflect the impact of the Reverse Stock Split.

Results of Operations

The following table sets forth certain data from our unaudited consolidated statements of operations expressed as percentages of net revenue:

Non-GAAP Disclosure

In addition to the financial information prepared in conformity with GAAP, we provide certain historical non-GAAP financial information. Management believes that these non-GAAP financial measures assist investors in making comparisons of period-to-period operating results and that, in some respects, these non-GAAP financial measures are more indicative of the Company’s ongoing core operating performance than their GAAP equivalents.

Management believes that the presentation of this non-GAAP financial information provides investors with greater transparency and facilitates comparison of operating results across a broad spectrum of companies with varying capital structures, compensation strategies, derivative instruments, and amortization methods, which provides a more complete understanding of our financial performance, competitive position, and prospects for the future. However, the non-GAAP financial measures presented in this Form 10-Q have certain limitations in that they do not reflect all of the costs associated with the operations of our business as determined in accordance with GAAP. Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. Further, the non-GAAP financial measures presented by the Company may be different from similarly named non-GAAP financial measures used by other companies.

29

Non-GAAP Net Loss

Management uses non-GAAP net loss (defined as net loss before interest, taxes, depreciation and amortization and stock-based compensation) in its evaluation of the Company’s core results of operations and trends between fiscal periods and believes that these measures are important components of its internal performance measurement process. Management believes that this non-GAAP financial information reflects an additional way of viewing aspects of our business that, when viewed with our GAAP results, provides a more complete understanding of factors and trends affecting our business. The following table contains a reconciliation of non-GAAP net loss to GAAP net loss attributable to common stockholders (in thousands):
